libre-licensed.  "open" leaves the possibility of accusations of "fake open

"we'll release the code when it's revision 1.0... but it's open!".

"we'll release the code when it's ready... but it's open!"

"we'll release the code... under a non-commercial license... but it's open!"

no, not OpenCL.  that has to come later as we'll need an entire new
grant to do it.

and piss people off :)

looks good.  i'd put "target multiple SMP cores" though.  "more cores"
could mean "NUMA" or "SIMT".  SIMT is almost impossible to program for
general-purpose, and NUMA is a royal pain, memory-wise.
